Meat from under the saddle is lethal if consumed, and horse liver is also inedible because injuries inflicted by whips tend to accumulate in the liver.

[Invention] According to: *Lingshu Jing* states that sudden facial paralysis with stiffness causes the eyes to remain open; heat causes flaccidity of the sinews. If the eyes cannot open, it is because cold in the cheek sinews causes stiffness, pulling the mouth corner. Heat causes relaxation and inability to control the muscles, resulting in deviation. Treatment involves using horse fat (Magao) applied to the stiff side of the cheek to soothe it, and a mixture of white wine and cinnamon twig (Guizhi) applied to the relaxed side.

Apply horse fat compresses to the stiff cheek while drinking fine wine and eating roasted meat. Those who do not drink alcohol should force themselves to do so. Perform three manipulations (fupai). The world largely ignores the efficacy of this prescription. I believe facial deviation is caused by wind pathogen invading the vessels. The Yangming meridians of the hand and foot traverse the mouth, and the Taiyang meridian converges at the eyes. Cold causes sinew stiffness and deviation; heat causes sinew flaccidity. Thus, cold on the left forces heat to the right, and cold on the right forces heat to the left. Cold causes stiffness, heat causes flaccidity. On the stiff side, the skin is numb and obdurate, with stagnant Ying and Wei qi. The treatment principle is: soothe the stiff, and tighten the flaccid. Therefore, use the sweet, neutral, soft, and soothing properties of horse fat to massage the stiff area, moisten the obstruction, and unblock the blood vessels. Use the pungent, hot, and binding nature of cinnamon wine to apply to the flaccid area, to restrain flaccidity, harmonize Ying and Wei, and unblock the meridians.
